Sweden-Sweden (SE) 7605253-9 (71) (72) Paul Manfred Persson, Flintvägen 20, S-175 61 Järfälla, Sweden-Sweden (SE) (7 * 0 Oy Koi ster Ab (5 * 0 from observation sites to central locations specifically for military purposes -System for attending to flertal observation sites information for central observation sites, for example for military purposes

When studying how different units, such as certain artillery and missile units, combat vehicles, airplanes, etc., behave in a combat situation organized for training, there are observers in or near different operational units. Observers report verbally via radio to the central reception site how various events develop in a combat situation. Reporting can concern, for example, finding a target, reporting a target, fire, estimated hit, etc. At the receiving site, each operating unit is given a separate channel in an on-site registration device, a multi-channel recorder. A common time code is registered for all channels. After the completed registration, in most cases after several successive steps have been performed, channel-by-channel listening is performed and protocols are drawn up which, taken together, form the basis for the evaluation of the experiment.

Due to the manual procedure, it can take a long time after a combat situation has occurred for the estimated result to be at hand. Therefore, the question has been raised as to whether the automation of data processing could not come into question 66250. The procedure can, of course, also be used in the context of concrete combat situations.

It seems quite reasonable that the information to be transmitted in a combat situation can be structurally expressed by a relatively limited number of predetermined sentences. The present invention is therefore based on the use of encoded, preferably binary, encoded communication instead of verbal communication. Each observer is therefore equipped with a device equipped with a set of keys. Each individual key represents a specific piece of information and is assigned a specific code. The encoded information is preferably transmitted via a radio connection to the receiving location where it is registered (stored). The information is now here in such a form that it can immediately become the subject of automatic data processing.

The quality of the system according to the invention is apparent in more detail from the appended claims.

During one step, i.e. within a given contiguous chain of events, the amount of data likely to remain relatively limited, even in an extended system, and processing is limited at least in the first step to simple sorting and presentation, allowing the use of a limited size on-line connected computer (minimizer).

The system should be able to implement most of the existing standard units and available components. The code for data transmission is, for example, the so-called Teletype code, which is commonly used in computer connections. Teletype code is an extension of ASCII code that is standardized (ISO / R 648). The code contains 64 (te. 2 ^) data-bearing characters (letters, numbers, characters), which provides external frames for a set of keys for formatting. The data-carrying keys also have a HUB-OUT key, which is used in connection with error strokes. The keys may have built-in lamps that light up when pressed, or the device may also have a monitoring display that indicates which keys have been pressed in a particular detection situation.

The coded information obtained from each key pressed is transmitted and transmitted in serial form. The baud rate is normally 10 characters per second, i.e. 110 baud. The transmission of binary coded data takes place wirelessly on separate wavelengths or channels for different monitoring locations. The modulation is preferably by means of a subcarrier.

An embodiment of a system adapted according to the invention will now be described with reference to the accompanying drawing, which shows in the form of a block diagram how the system can in principle be advantageously constructed.
